<h4 id="3-适配器的解释："><a href="#3-适配器的解释：" class="headerlink" title="3.适配器的解释："></a>3.适配器的解释：</h4><p>方法一：构造方法要注意数据的获取,参数传递的问题,要拿到图片，文字数据下面才能布局</p>
<p>方法二 :getCount返回数据组数大小(size)</p>
<p>方法三:getItem返回当前item  </p>
<p>方法四 :getItemId返回position</p>
<p>前四个方法写法都比较简单</p>
<p>方法五 ：自定义一个ViewHoder内部类,其中在构造方***法中来初始化xml组件<br>其中CircleImageVie是加了依赖后才可以用的组件    </p>
<pre><code>class ViewHoder{
    CircleImageView iv;
    TextView tv;
    public ViewHoder(View view){
        iv=view.findViewById(R.id.item_star_iv);
        tv=view.findViewById(R.id.item_star_tv);
    }
}</code></pre><p>方法六(核心):View getView<br>关于converView: 首先我们要知道setTag方法是干什么的，他是给View对象的一个标签，标签可以是任何内容，我们这里把他设置成了一个对象，为了实现复用,使用getTag和setTag实现复用<br>convertView作用：这个convertView其实就是最关键的部分原理上讲当ListView滑动的过程中 会有item被滑出屏幕而不再被使用，这时候Android会回收这个条目的view 这个view也就是这里的convertView当item1被移除屏幕的时候 我们会重新new一个View给新显示的item_new 而如果使用了这个convertView 我们其实可以复用它 这样就省去了new View的大量开销</p>
